5. STORAGE - HANDLING OF COMPONENTS
5.1 STORAGE CONDITIONS
Store in a well ventilated environment with the following relative temperature and
humidity range: -10° to 60°C ; 85% HR maximum.
Store without contact with the ground, on a pallet or platform, a clean dry surface
until the packages are retrieved for production.
Store packages away from water and direct UV rays.
Store packages away from heat and areas with high temperature variations.
Keep away from high temperature or hygrometry variations to avoid
condensation inside the packages.
Store packages away from dust to keep the components clean.
Keep packages as they are delivered, without undoing the adhesive ribbon until
use.
Do not walk or place heavy objects on packages.
Where packages are stored in racks, place the heavier cartons below and the
lighter ones above not to damage the parts.
5.2 HANDLING OF COMPONENTS
Do not touch the terminal contact points or the interior of the barrel.
In the event that the terminal must be handled, please wear gloves in order to
prevent corrosion.
Placing items on top of a terminal or dropping a terminal may result in shape
deformities or contamination. Please handle terminals with care.
In the event of terminals becoming tangled, please do not forcibly pull or bend
them apart, but disentangle them carefully.
Use caution when handling terminals so as to avoid deformation.
Make sure that the terminals of crimped cables do not become entangled. When
bundling or stacking cables, please prevent the terminals from being subjected to
any external force.
Use caution to ensure that the part is not subjected to any large impacts.

Do not place wire harnesses on the floor.
Refrain from any handling that may result in terminal damage or deformation.
Do not use the housing in case it drops.

6. ASSEMBLY PROCESS
6.1 CRIMPING OF TERMINALS
1 - Strip the cable
Please refer to the Crimp Quality Standard (§10) for details on strip length.
2 –Crimp wire in terminal
Note 1: Please use the Hirose crimp tool.
Note 2: Please refer to the Crimp Quality Standard (§10) and the crimp parameters (§11) by
cable to check crimp condition.

6.2 CONNECTOR ASSEMBLY INSTRUCTIONS
1 –Insert contact and push until a click is heard.
Please take care not to insert the terminal in the opposite orientation.
Straight insertion (Correct):
Note 1: Holding the cable, please insert straight into the housing.
Note 2: If the crimped terminal does not enter the housing smoothly, remove and then re-insert it.
Angled insertion (Incorrect):
Up-down Direction (Incorrect) Right-left Direction (Incorrect)
Scoop and twisted insertion (Incorrect)
Note：Do not use excessive scooping or twisting when inserting terminals.

＜Precautions When Inserting Terminals＞
When inserting terminals, hold the socket and insert the terminal without touching the lock lever
(circles in red on the picture below).
2 –Make sure that the contact lance is hooked by the housing lance of the socket.

7. WIRING HARNESS ASSEMBLY RECOMMENDATIONS
Deformed or damaged parts have to be replaced by a new one.
Apply tape so that every individual wire is subjected to an equal amount of tensile
force to avoid any effect on terminals (like disengagement).
The distance to apply tape from the end of connector is 35mm minimum.
The bending radius for wires should be at minimum 3 times its outer radius to
ensure normal use of our connectors.

8. REPAIR PROCESS
For removing the inserted contact from the socket, lift up the housing lance by using a pointed
needle, and pull out the cable.
Once removed, socket cannot be re-used. Please use a new part after repair is completed.
